Panel Compatibility

The Siemens BQ2B070 is a bolt-on style breaker from the Siemens BQ/BL/BA series, designed to mount in compatible Siemens/ITE bolt-on panelboards and loadcentres — including select EQ, ES, PL, and PN series panels that accept bolt-on breakers. As a 2-pole, 70A, 240V unit with a 10kA interrupting rating, it is well-suited for branch-circuit protection in both residential and light commercial applications.

Bolt-on breakers are not interchangeable with plug-on (QP/QT) style loadcentres — please verify your panel accepts the bolt-on style before ordering. Send us your panel model number and we'll confirm fitment.

The BQ series uses a bolt-on mounting method, where the breaker is physically bolted to the bus bar — providing a more secure mechanical connection. The QP series uses a plug-on design that clips directly onto the bus. These two styles are not interchangeable, so it's important to confirm your panel accepts bolt-on breakers before purchasing the BQ2B070.

Yes — the BQ2B070 is a 2-pole breaker rated at 240V and 70A, making it appropriate for protecting double-pole 240V circuits such as electric dryers, large appliances, EV charger circuits, or as a feeder breaker for a small sub-panel, provided your installation meets all applicable Canadian Electrical Code (CEC) requirements.
